ć¦ććć2. Description of the Related Art Conventionally, the content of a specific chemical component contained in a sample solution or its activity value and the content of a formed component are quantitatively analyzed simply by spotting and supplying small drops of the sample solution. A dry-type integrated multi-layer analysis film (multi-layer analysis element, multi-layer analysis element) that can be used has been developed and put into practical use. Further, a filter paper type test piece and an improved single-layer or multi-layer test piece have been proposed, and some of them have been put into practical use.

In the case of the non-containing one, it is spotted directly on the reagent layer, and then it is kept at a constant temperature (incubation) for a predetermined time in an incubator (incubator) to cause a color reaction (dye forming reaction), and then a predetermined amount in the sample solution. The optical density of the chemical analysis slide is measured by irradiating the chemical analysis slide with irradiation light for measurement including a wavelength preselected by combining the biochemical substance and the reagent contained in the chemical analysis slide, and the optical density value is obtained in advance. Obtain the substance concentration or activity value of the specified biochemical substance in the sample solution using the calibration curve that shows the correspondence between the optical density value and the substance concentration or activity value of the specified biochemical substance. It is intended.

Then, for automatic operation, the dry analysis film piece is used as a chemical analysis slide housed in a slide frame (frame) made of an organic polymer. By putting the dry analysis film pieces in the slide frame, the dry analysis film, which tends to warp when dried, can be kept flat.

ć¦ććć®ć§ćććThat is, the reagent in the reagent layer does not react without water, but the reaction may start as soon as the water is absorbed. Therefore, in order to obtain an accurate analysis result, the reagent layer must be kept dry until the measurement is performed. However, since the dry analysis film piece is liable to warp when dried, when the dry analysis film piece was kept in a dry state, the dry analysis film piece was curved in a tile shape. Therefore, in order to keep the curved dry analysis film piece in a flat state, the dry analysis film piece is forcibly placed in a frame to be in a flat state.

That is, in a large medical institution, a large cartridge is used because a large amount of chemical analysis slides are consumed within a short time, and it is necessary to provide a number of cartridges corresponding to the number of biochemical substances to be analyzed. Therefore, the space required for the cartridge is large.

Although it is preferable that the dry analysis film pieces from the cartridge be adsorbed by the adsorption pad and taken out, as described above, the dry analysis film pieces in a dry state are curled like a tile. It is easy and the degree of curvature changes according to the spotting of the sample liquid.The sample liquid is accurately spotted on this dry analysis film piece, and the dry analysis film can be exposed without touching the spread sample liquid. The pieces must be transported to the incubator.

First, as shown in FIG. 4 (A), the suction pad 17 enters the second opening 29b of the outlet 29 from above and abuts the base 2 of the uppermost dry analysis film 1 to enhance the adhesion. Then press it further as shown in Fig. 4 (B). At this position, the suction pad 17 holds the dry analysis film 1 by the suction force of the suction pump. Next, the suction pad 17 rises as shown in FIG. 4 (C) while adsorbing the dry analysis film 1, and both side portions of the dry analysis film 1 are contacted and supported by the edge (receiving) of the second opening 29b. In addition, the dry analysis film 1 is formed and stopped so as to have a predetermined curved shape.
Then, as shown in FIG. 4 (D), the suction pad 17 slides toward the first opening 29a side, and the dry analysis film 1 is moved to the first opening 29a side.
It is taken out to the outside through the opening 29a. In addition,
By the above forming, the curl shape of the dry analysis film 1 in a dry state is forcibly made into a predetermined curved shape,
The openings 29a are surely passed one by one.

While being held by the suction means 17, the spread layer 4 is turned upside down so that it is conveyed to the insertion position of the incubator 102. Then, when the empty cell 142 is moved to the insertion position by the rotation operation of the main body 140, the opening / closing drive mechanism 177 is driven to operate the pair of opening / closing arms 178 so that the distance between the tips of the opening / closing arms 178 increases. , Fig. 13
The slide plates 175 on both sides of the shutter 174 are opened as shown in (A). At that time, the film presser 161 is stopped at the upper part. In this state, the dry analysis film 1 after the spotting, which is held downward by the adsorbing means 17, is lowered, and as shown in FIG. 13B, the dry analysis film 1 is held by the film holder 161.
Then, the opening / closing drive mechanism 177 is driven to close and the slide plates 175 on both sides of the shutter 174 are closed. As a result, as shown in FIG. 13 (C), the dry analysis film 1 is moved upward and the film retainer 161 and the shutter are pressed.
It is sandwiched between the slide plate 175 and the slide plate 175, and the spotting surface on the lower surface side is held in a sealed state by the shutter 174. After that, the suction means 17 is moved upward by the transport means.

容ęćØćŖććć®ć§ćććAccording to the present invention as described above, the cartridge is arranged so that the outlet is located at the upper side or the lateral side, and the dry analytical film piece is adsorbed from the cartridge from the upper side or the lateral side. After taking out the sample solution, the sample solution was rotated so that the substrate was on the bottom surface in the same adsorption and holding state before it was spotted, and after spotting it was transferred to the incubator and inserted into the internal cell. As a result, good transport can be performed with a simple transport mechanism, and reliability can be secured.
In addition, a dry analysis film strip without a slide frame can be used, and the size of each biochemical analysis device can be reduced by downsizing and downsizing, and the analysis cost can be reduced by eliminating the slide frame. Therefore, it is possible to improve the processing capacity, and further, to reduce the portion to be contaminated to facilitate maintenance.
